Description

This invention relates to a water valve assembly.
There is a known safety issue associated with any water valve arrangement that allows hot or boiling water to be dispensed from the same due to the risk of a user accidentally burning themselves on the water being dispensed therefrom. In an attempt to overcome this problem, it is known to provide a safety button on the valve arrangement that needs to be actuated in order for the thermostatic control of the tap or valve arrangement to be adjusted. One such example is a red button provided on a thermostatic shower mixer tap. The user has to knowingly actuate the button in order to allow hot water to be dispensed using the tap. This helps to remove the risk of a user accidentally increasing the temperature of the water. The safety button is particularly advantageous when a user is a child or an elderly person. However, a problem with the abovementioned arrangement is that a child or elderly person could still actuate the safety button, either by accident or deliberately, thereby increasing the risk that a user could burn themselves on the water being dispensed from the water valve assembly. A similar problem is encountered with boiler taps. In addition, it is noted that the safety button arrangement can fail due to failure of a mechanical component associated with the same.
US 2012/234409 A1 discloses a display apparatus for affixing to a shower of bath water supply to provide authorisation means to activate water flow.
WO 2016/040986 A1 discloses a fluid dispensing system, system for processing waste material, a fluid monitoring system, and a method for monitoring the quality of a fluid.
US 6 315 208 B1 discloses a method and system for providing temperature-sensitive water delivery using thermostatic controls on home plumbing systems such as showers, sinks and bathtubs.
It is therefore an aim of the present invention to provide a water valve assembly that overcomes the abovementioned problems.
According to the present invention there is provided a water valve assembly as set out in the accompanying claims. Preferred features are set out in the sub-claims. Thus, there is provided a water valve assembly, according to the features of independent claim 1.

Embodiments of the present invention will now be described with reference to the following figures, wherein:
Figures 1-9 each show a perspective view of a water valve assembly, a water tap, including fingerprint recognition means according to different embodiments of the present invention.
Referring to figures 1-3, there are illustrated water valve assemblies, water taps 2, having water dispensing outlet means in the form of a spout 4, user actuation means in the form of a rotatable handle 6 and a display portion 8. The tap 2 is typically arranged at a suitable location on or adjacent a sink, faucet, basin, worksurface and/or the like in use.
In the illustrated examples the spout 4, handle 6 and display portion 8 form a single tap unit. However, it will be appreciated that the spout, handle and/or display portion could be separate if required.
It will be appreciated that the water dispensing outlet means or spout, the tap, the handle and/or the display portion can be any suitable size, shape and/or design.
The rotatable handle 6 includes an outwardly protruding gripping portion 10 to allow a user to easily grip and actuate the rotatable handle 6 in use. The handle 6 is movable between an "off" condition, wherein water cannot be dispensed from the spout 4, to an "on" condition, wherein water can be dispensed from the spout 4 in use. Actuation of handle 6 typically actuates a valve arrangement located internally of the tap which is not shown.
The display portion 8 is attached to the main body portion of the tap 2. It includes a temperature display 12 which displays the water temperature that will be dispensed from tap 2 when in the "on" condition in use. An "on"/ "off" power operational button 14 is provided which allows the tap, or at least the heating element of the tap, to be moved between "on" and "off" operational conditions in use, a "+" button 16 to allow the temperature of the water being dispensed from the tap to be increased in use, and a "-" button 18 to allow the temperature of the water being dispensed from the tap to be decreased in use. In addition, in accordance with the present invention, a fingerprint sensor 20 is provided on display portion 8 to allow detection, recordal and/or verification of a user's fingerprint in use, and particularly to allow detection, recordal and/or verification of specific characteristic features of a user's fingerprint in use.
According to the invention, the tap 2 is arranged to only dispense water below a predetermined temperature, such as for example below 38°C, when the handle 6 is in the "on" condition unless a fingerprint recognition process is positively or successfully undertaken by a user. If a positive or successful fingerprint recognition process is undertaken, for example a user's fingerprint detected by sensor 20 matches identically a pre-stored user's fingerprint, then the user is able to change, increase, or decrease the temperature of the water being dispensed from tap 2.
Micro-processing means are typically provided with or associated with the display portion 8 to allow actuation and/or control of the power button 14, the temperature adjustment button or buttons 16, 18 and/or the fingerprint sensor 20.
The micro-processing means can be provided in the display portion 8 or could be provided remote to the display portion 8, such as underneath a sink or worksurface associated with the tap 2 in use.
The micro-processing means and/or the elements on the display portion can be powered by mains power, generator power, solar power, battery power and/or the like.
In one method of operation of the present invention, once the power button 14 has been moved to an "on" or operational condition, a user can have access to a user menu, such as for example, by holding the temperature + or - buttons 16, 18 down together. Access to the user menu protected by requiring input of a user's pin or unique code if required.
There are a number of ways in which a user who wishes to be authorised to use the tap in use could store their fingerprint data in memory associated with the micro-processing means.
An example of one method is where the user scans an image of one of their fingers a pre-determined number of times, such as for example three times, using the fingerprint sensor 20 during a recognition option in the user menu. The display portion 8 could confirm user fingerprint registration once the process has been successfully completed.
Once a user has been registered as being an "authorised user" for the tap, in order to adjust a temperature of the tap in use, the user places their authorised finger on the fingerprint sensor 20 (when the display portion was in a power "on" operational condition) and await recognition of their fingerprint by the micro-processing means. On recognition of the fingerprint as belonging to an authorised registered user, the user is then able to increase or decrease the temperature of the water being dispensed from the tap using the buttons 16, 18. If the micro-processing means does not recognise the user as being an authorised registered user, the user is not able to adjust the temperature of the water being dispensed from the tap.
In method, hot water above a pre-determined temperature threshold is only dispensed from the tap 2 on recognition of an authorised registered user's fingerprint by the fingerprint sensor 20 and the micro-processing means.
It will be appreciated that variations in the methodology for detecting the user's fingerprint, recording the user's fingerprint, verifying the user's fingerprint as being a match and/or operation of the tap and/or temperature control for the tap are possible without deviating from the scope of protection of the present invention.
Thus, it can be seen that the present invention provides increased security for a water valve assembly in order to prevent unwanted users from activating and/or accessing hot or boiling water. The present invention provides an alternative method to the conventional safety button method applied to many taps or thermostatic valves in the marketplace currently. The present invention also has the advantage that it is easier to use for less able users, such as elderly or disabled users, compared to conventional mechanically actuated safety buttons.
Figures 4-9 show further examples of water valve assemblies, water tap assemblies, according to the present invention.
Figure 4 shows a water tap 102 having an upright body portion 103, a spout 104 for allowing water to be dispensed from the same in use, and a display portion 106 associated with the top of tap 102. The display portion 106 is a touch screen display portion and so a user presses said display 106 in order to actuate one or more functions of the tap, such as moving the tap between a dispensing or "on" condition and a non-dispensing or "off" condition, for changing the temperature of the water being dispensed and for activating the fingerprint sensor 108. An icon of a tea cup 110 is shown so that water can be dispensed therefrom at a temperature suitable for making a hot drink.
Figure 5 shows a further example of a water valve assembly, a water tap 202, having two spouts 204, 206 for dispensing water therefrom. An actuation handle 208 is provided with spout 204 for dispensing cold water in a conventional manner through spout 204. Spout 206 is for dispensing hot water therefrom and is actuated via display portion 209. The spouts 204, 206 and display portion 209 are mounted on a plate member 211.
A fingerprint sensor 210 is provided on display portion 209 to allow authorised actuation of hot dispensing from spout 206 in use. Thermometer icons 212 on display portion 209 typically allow a user to adjust the temperature of the water being dispensed from spout 206.
The water tap 302 shown in Figure 6 is similar in design to water tap 202 shown in figure 5 apart from the shape of the spouts and actuation handle.
Figures 7-9 show different views of a water valve assembly, tap 402, having an upright stem portion 404. Actuation handle 406 protrudes outwardly from a lower part of stem portion 404 to allow the tap 402 to be moved between "on" and "off' conditions in use in a conventional manner. Fingerprint sensor 408 is positioned on an upper surface 410 of a rotatably mounted arm member 412. The sensor 408 works in a manner similar to that already described above. Arm member 412 protrudes outwardly from a central location of stem portion 404, in this example is arranged to be perpendicular thereto, and is rotatable about a longitudinal axis of stem portion 404 in use to allow the same to be moved out of the way of a user or sink if required. In particular, arm member 412 is arranged to be moved through approximately 90 degrees between the positions shown in figure 7 and figure 9.
A spout 414 is located at a top of stem portion 404 and protrudes outwardly therefrom to allow water to be dispensed from tap 402 in use. The spout 414 is arranged to be rotatably moved through approximately 90 degrees in use to allow the spout to be moved out of the way of a user or sink of required, between the positions shown in figure 7 and figure 8.
It will be appreciated that any or any combination of the above described features could be provided on a tap or valve assembly according to the claims.
